Platinum Metalic Gray, Black Dakota Comfort pkg, Cold weather pkg.
Any input on what these upgrades did to the gas millage? My exhaust lost me at least 2 miles per gallon.

I want to say about 9 months. I bought it last spring but didn't install it until the summer time. 
It's a great mod and in my opinion 10 times better than the Sprint Booster.
It just gets over looked because the install looks intimidating but I don't blame anyone that doesn't want to do the install themselves since you are tinkering with the ECU.
I did it myself following the BMS DIY pic by pic in about 2 hours taking my sweet ass time and have never looked back.

I have a sprintbooster V1. I am very interested in the Stage 3 manifold upgrade. Will it run in conjunction to the BMS pbx to get the 260hp? Also Is the BMS pbx really worth it over the SB V1?
